I'm torn here: I want to like this card since I like
, but it something doesn't seem right.
Is the cost too high? It's infinitely cheaper to play 3 sparks for 0 cost than 8+1 (lightning)
for the same result. So maybe it's just for an end-game attack boost? Hmmm..... But why not just use Immortals/Phase dragons? Sure, you'd have to wait another turn or so for a dragon, but it would have >3x the attack right off the bat.
But if you lower the cost too much....it'd be tempting to fractal it (particularly the upgrade). You'll burn one first turn (or maybe hold a Tower to play) then next turn play 4 upped cards and sacrifice them yielding 12 Ball lightnings resulting in 60 damage.
But wait--why use fractal when you can Twin Universe and do it all same turn? 8+6+6+6
yields 4 upped stargazers, then lightning to set it off. I'm sure the clever player will determine the right ratio of phase shields/towers to set this up effectively.
I think the unique value this card has is a sort of creature control deterrence (RoF in particular) but this is not a real issue for
anyway. Sorry, don't mean to be a downer on the card, but I'm not creative enough to see how to build it into an effective deck as is.
